10 Pack 18'' x 12'' White Corrugated Plastic Sign Blank Board Double Sided for Garage Sale, Rent, Birthday Party, Guidepost Decorations

These sign boards are perfect for everything from garage sales to birthday parties. I used them for a birthday party and the kids loved it. They were sturdy, double-sided, and easy to write on. Great value for the price!

Why did you pick this product vs others?: These are perfect for small protest signs. Get some acrylic markers and they hold up really well in the rain! LOVE THEM!

Corrugated Plastic is essentially glorified cardboard. However, corrugated plastic is made out of plastic, instead of the paper used to make normal cardboard. This results in a product that has several advantages vs normal sheets of cardboard. Specifiically corrugated plasic lasts longer than normal cardboard, is more resistent to normal damage than regular cardboard, and more resistent to water damage (i.e. the plastic doesn't get water logged). However, corrugated plastic is still almost as light as normal cardboard, and also almost as easy to cut to size. This makes corrugatated plastic a good choice for some "do it yourself" projects. In my case I needed a little material to make a small "shield" to protect some control buttons (on a power supply I owned) from the cats stepping on those buttons (thereby changing the power supply's settings). Since I didn't need a large shield (just one big enough to easily cover the power supply buttons), I figured corrugated plastic was a good choice (as it is VERY EASY to cut the proper size and shape). Since I couldn't find any old corrugated plastic around the house, I bought this set from Amazon. Yes, this set was sold for making yard signs (and it would likely work well for that purpose), but since these are still corrugated plastic sheets I could easily cut down one of these sheets to make my power supply button shield (which I then attached to the power supply with double-sided tape, with duct tape covering the top of my "shield").

It's the same quality as you would find at Home Depot. The only issue is they were stuck together and made it look like two were one sheet.

I was glad to find signs that didn't come with lawn posts. I used these in a protest. The dimensions are good for holding for a long period of time, without being too hard to keep in the air worked great!

very sturdy and reasonably priced for as heavy as it is. Good stuff.

Good signs but I missed that these do not include the stakes for lawn setup

These plastic pieces are perfect for protest signs. I had a friend staple lathe strips to them for handles. The surface is easy to letter on. They are sturdy and hold up in rainy weather. Recommended.
